To calculate the total cost of the meal including a 13% tip in one step, Nathaniel can multiply the cost of the meal by \(1 + 0.13\).

Here’s the breakdown:

1. The tip is 13%, which is expressed as a decimal as 0.13.
2. To find the total amount after adding the tip, you take the original amount and add the tip:
\[
\text{Total} = \text{Cost of Meal} + \text{Tip}
\]
This can be expressed as:
\[
\text{Total} = \text{Cost of Meal} \times (1 + 0.13) = \text{Cost of Meal} \times 1.13
\]

Therefore, Nathaniel should multiply the cost of the meal by **1.13** to find the total including the tip in one step.
